Abstract (en)
[origin: DE19949091A1] The invention relates to polyester-polyether block copolymers which can be produced by the catalytically induced attachment of alkylene oxides to H functional starting materials. Said copolymers are characterised in that polyester alcohols are used as the H functional starting materials and multi-metal cyanide compounds are used as the catalysts.
